What is YK-11 – imuscle UK

What is YK-11

YK-11 is part of SARMs (selective androgen receptor modulators), but its action differs radically from that of other supplements in the group. The mechanism by which UK 11 acts differs from other SARMs in that it blocks the hormone myostatin.

YK 11 has not been sufficiently studied in humans, so its use should be controlled. Good results often arouse the desire for a longer cycle, but should not be overdone. We have prepared answers to the most frequently asked questions to help you understand if UK11 is for you!

Clinical trials on YK 11

Muscle atrophy is one of the first conditions on which this SARM has been tested. The data show that it increases the mass of the injured muscle or muscle group after immobilization or as a result of severe illness.

Studies in mice have shown that YK-11 has a beneficial effect in the presence of sepsis (a purulent infection of the body). Mortality in sick mice has dropped dramatically, and scientists have found that this SARM has potential as a cure for muscle weakness caused by bacterial sepsis and other conditions.

Does YK 11 Myostin enter the doping list?

Myostin is on the border between SARM and a steroid. Its powerful action gives an exceptional advantage in power sports and in professional sports circles in general. Due to its anabolic function, its use was banned by the World Anti-Doping Agency on December 12, 2012.

What are the benefits of Myostin YK 11

Are you tired of giving 101% of yourself in the gym, but the results are half as small as those of the trainees around you? We are all born unique and have different structure and muscles. This structure is primarily influenced by the genetic potential we inherit from our parents.

Myostin YK 11 has many benefits, but the most significant is its ability to increase muscle mass to levels that exceed genetic potential. That is, even if you are not generous and muscular, YK-11 can help transform your body forever. Bodybuilders often use this SARM for just that.

It is suitable for people with a bad gene, who, no matter how much they train, do not see a huge difference. What is remarkable about this SARM is that it exceeds the limit of muscle growth. Steroids work, but are also affected by the limit of the hormone Mistotatin in the body. However, YK-11 has the unique property of suppressing it and increasing the пpeptide Folistatin. 

If you have inherited from your parents a lean physique, a difficult increase in muscle mass, or you are middle-aged and your body is already getting into shape very slowly, YK-11 is just for you! Here are its most common benefits:

  • Myostine YK 11 doubles muscle mass
  • Stimulates endurance and strength
  • Develops male characteristics, and protects against the action of the female hormone estrogen.
  • Supports muscle density
  • Increases muscle tone

YK 11 Myostin for gaining muscle mass

People who have tried Myostin say that they notice an increase in muscle mass after the first week of intake. Some argue that the visible effect comes at the end of the second week. In both cases it depends on how much you train and load the muscles, as well as on the overall condition of the body.

However, there are no two opinions about the effectiveness of Myostin! In animal research and during experimental use by bodybuilders, athletes and fitness professionals, the YK-11 has shown remarkable results. The benefit of it for increasing muscle mass is unparalleled, because despite its powerful action, when taken properly, its side effects are minimal.

YK 11 Myostine for durability and strength

YK-11 durability and strength

You are in good shape, you have perfected your best training, you are happy with your appearance and you seem to have reached the peak of your abilities. Now what? Do not give up! With Myostine you will gain completely new levels of endurance and strength that you did not know you could have.

This SARM is perfect for the moments when you stick to a few pounds and a degree of difficulty in training, because you fail to improve them. This is completely normal for the body, precisely because of the hormone myostatin, which you can suppress by taking YK-11.

Of course, a surge of such strength and endurance can be achieved with a steroid cycle, but how many people would like to worry about their side effects such as hair loss, hirsutism in women, acne, and many others.

YK-11 protects against the action of estrogen

The structure of Myostina is very similar to that of dihydrotestosterone (DHT). It in turn is responsible for hair growth, muscle stiffness, explosive power, and increased libido.

This property of DHT protects against the action of estrogen, which in turn leads to increasingly noticeable male scars. UK-11 will lower the female hormone in the body, so it is not recommended for women, as there may be health risks.

YK 11 Myostin helps muscle density 

Androgens are key regulators that play an important role in the male reproductive system. They have an anabolic effect on bone density and skeletal muscle mass. If you are looking for a supplement to harden your muscles, Myostin may be helpful.

There is a study according to which muscle firmness and density is based solely on genetic predisposition. Yes, but UK11 refutes this claim!

In a 2018 mouse study, it was found that this SARM had a beneficial effect on muscle density. You can read the results of this experiment on the website of the National Library of Medicine.

How Myostin YK-11  works

YK-11 action
  • Shows anabolic activity
  • Builds muscle and gives strength like DHT
  • Increases the peptide follistatin

Myostatin (differential growth factor) is a hormone without whose action a person's appearance would be much different. Its role in our body is to synthesize a protein that blocks the growth of muscle tissue.

Myostin YK-11 is a SARM that suppresses said hormone, leading to an increase in the follicle peptide.. It in turn causes muscle growth beyond the body's capabilities.

The expression of anabolic activity in YK-11 is thought to be many times greater than that of testosterone. And consumers are happy with the effect on building muscle. According to those who have taken it, it acts more strongly than dihydrotestosterone (DHT).

Most notably, in animal studies, weight gain without accumulating almost any fat was considered. In a publication of PNAS magazine in 2007. it is clear that mice that do not have a myostatin-suppressing gene have exactly twice as much physical strength as others.

The lack of myostatin (which YK-11 inhibits) promotes the growth of skeletal muscle mass, demonstrating a powerful mechanism by which muscle size can be controlled in normal mice. According to research, when taking this SARM, atrophied muscles were also stimulated to grow and regain strength.

When are the first results of YK 11 seen

Yk-11 is super effective in building muscle mass regardless of genetic potential. Of course, its intake accompanied by strength training will show the best that this SARM is capable of. Since it has been little studied on humans, the only way to understand how fast it works is animal research and consumer opinion.

If you are serious in the gym with this supplement you will be able to gain lean muscle mass so fast that your friends will want to know what your secret is. Some athletes who take SARM report that Myostin works almost instantly, and with the help of intense training, the results are like a magic wand.

But when do you see the first results of YK 11? The Department of Internal Medicine at Yale University found that treating mice with this myostatin suppressant showed a drastic increase in strength over 4 weeks. You can read all the information and benefits of this study here.

Although more research is definitely needed, according to initial data and stories from people who have already touched on its effect, it is clear that Myostin acts very quickly, ahead of even the strongest anabolic steroids.

Does Myostin YK-11 act on testosterone production

Myostin YK-11 has a depressant effect on the body's natural production of testosterone. Many users say they feel their levels drop just like anabolic steroids only after 4 weeks of use. Post-cycle therapy with this SARM is a must!

In case of abuse and a cycle that is too long with YK 11, total uptake of androgen receptors is observed, which interferes with their connection with the male hormone. This is because myostin is highly anabolic and binds first to receptors. Then over 60% suppression of the body's own hormone production can be observed.

Selective androgen receptor modulators do not have as many side effects as steroids, and after taking some of them, you do not even have to do rehabilitation therapy. YK-11, however, is on the borderline between SARM and an anabolic steroid, so more care should be taken with it.

How to cycle with YK-11 Myostin

The duration and dose of the Myostin cycle may depend on many factors. We do not recommend that you start taking it recklessly if you have no experience in bodybuilding, as well as in taking such supplements.

For starters, you can choose a shorter but effective cycle that includes 5mg. per day for a maximum of 6 weeks. This is a time when you can see for yourself its strength and get amazing results. Since your strength and endurance will be light years from before, we advise you to give the maximum in the hall to achieve a "wow" effect.

If you are advanced, you can take 15-20 mg. per day, not exceeding the duration of the cycle more than eight weeks. These are data collected from personal experience and impressions of people in the field of bodybuilding.

  • Beginners - 5-10 mg / day
  • Advanced - 15-20mg / day

Muscle mass cycle

YK-11 for Muscle Mass

YK 11 Myostin in a muscle mass cycle is its most common use because of the good effects it gives even after a week. The dose depends on your experience and ambitions. It is always safer to start with a low dose, which is gradually increased.

As YK 11 is still an experimental drug and was not designed specifically for bodybuilding and fitness environments, the dosage can be adjusted according to the needs of each user. That is, you can start your first cycle with this SARM with 5mg. per day, increasing the dose after a few weeks. However, post-cycle therapy is mandatory!

If you already have experience and know how to properly do a SARM cycle with YK 11, plus you have knowledge of rehabilitation therapy after it, you can start with 10mg. and increase the dose gradually. Reviews show that it makes no sense to exceed 20 mg. per day because there are no additional benefits and the risk of serious side effects increases.

Cycle for strength and endurance

YK-11 is undoubtedly a very good helper to improve strength if you do bodybuilding or want to exceed your abilities in the gym. In about two weeks, you will feel this effect regardless of the dose you take.

Here, too, the reception depends entirely on you and your feeling. The lowest dose that is suitable for beginners is 10 mg, and the upper limit is 15 mg. per day. Start with a small dose, as YK-11 will increase your strength quite quickly and you do not need to risk your health to see good results.

Fat burning cycle

Myostin has the natural ability to clear fat and prevent it from accumulating when taken in a cycle for muscle mass or strength. However, YK 11 is not usually taken on its own in a fat-clearing cycle, as its main effect is different.

YK 11 Myostin in a cycle for sports disciplines

Myostin is not suitable for people engaged in martial arts because of the fast and powerful effect it has on gaining muscle mass. This effect will slow down the movements of athletes and instead of benefit, will be an obstacle to success.

However, bodybuilders are the ones who enjoy the positive influence of Myostin on their bodies. Superman strength and extremely fast growth of muscle fibers are among the most sought after results. That is why this sport is the main one in which YK 11 finds application.

Cycle with YK-11 for women

Unless you are a professional bodybuilder, we do not recommend women to take Myostin as this SARM is too strong. There are other SARM supplements, such as Stenabolic, Andarin and Cardarine, which are ideal for women and have no effect on hormones.

Best SARMs stacks with YK-11

YK 11 Myostin, as one of the strongest SARMs, should be carefully combined with other SARMs of this type. Most people agree that YK-11 works more than effectively on its own for pumping.

UK11 can be combined with Ligandrol and RAD-140 for bulking, or with Ostarinee and Cardarine for extreme fat burning while gaining muscle mass in negative time. Who wouldn't want that?

Another popular stack is YK-11 + Ibutamoren, as Ibutamoren is known to act as a growth hormone, raising the body's HGH levels. By combining these two SARM products, you could make significant progress in terms of size and strength.

In order to provide you with the most useful and accurate information, we researched which are the best stacks with Myostine according to the general opinion.

stack Myostin + Testolone + Ibutamoren

This SARM stack is for anyone who wants to make more progress in strength training, but can not do it only with their own genetic data. Misotin in this combination will really get the most potential out of your body, and the results can be from 5 to 6 kg increase in lean muscle mass in less than 6 weeks.

The formula for the success of this trio is the regulation of myostatin, increasing the production of growth hormone, as well as stimulating protein synthesis, which speeds up metabolism and dramatically increases strength.

stack Myostin + Ligandrol + RAD-140 + Testolon

With these four products you will not feel how fast you will transform your body! This is a stack with the most powerful SARM products, which can benefit even the laziest in the fitness environment. That is, with minimal effort you can achieve results that will make people gasp.

If you want to build muscle mass as quickly as possible and gain exceptional strength, this is your stack! It is the most popular and preferred among successful bodybuilders and fitness enthusiasts.

How to determine the quality level of YK-11


SARMs are not regulated on the market, so it can be very difficult to find an original product at an affordable price. The quality level of YK-11 can only be determined in a registered laboratory.

Unfortunately, too much of Myostin sold in Bulgaria has a very small percentage of selective androgen receptor modulators, at the expense of other ingredients, which are often unapproved drugs.

The brand from which you plan to buy UK11 must be able to provide you with a quality test of the respective product. Don't trust the marketing "MADE IN" trick. Made in US / UK / Germany does not mean anything other than that the product is packaged in that country.

What are the side effects of YK-11

YK-11 Side Effects

SARMs are arguably a better alternative to steroids when it comes to side effects. However, some SARMs are safer than others because each supplement works differently.

The side effects that we know today about YK-11 are largely formed by the experience of people in the field of bodybuilding and fitness. Myostin is a selective modulator of androgen receptors and a steroid at the same time. This raises the question of how safe it is to use and can anyone take it?

Real side effects 

There are several well-known side effects of Myostin YK-11 and they are:

  • enhanced hair growth
  • suppression of testosterone levels after 4 weeks of intake.

Some users who generally suffer from high blood pressure notice an increase in blood pressure. The enormous power of UK11 often causes a change in mood, consisting mainly of increased aggression.

Myths and unrealistic claims about the side effects of Miostine

It is good to know that each organism can react differently to Myostin. YK-11 is a powerful SARM and can negatively affect the body in various ways. However, its selective action makes it more harmless than anabolic steroids and many of the side effects of Myostin written on the Internet are myths and unrealistic claims!

None of the studies performed on UK11 indicate that this SARM:

  • Increases the risk of heart attack
  • Stops your own testosterone production
  • Negatively affects the liver

These claims of side effects are more myths than statistically substantiated facts. It is important, of course, to take YK11 wisely and in acceptable doses!

How to do post-cycle therapy with YK 11 Myostin

SARMs are known to mean that post-cycle therapy is not mandatory in most cases. However, when using YK 11, we recommend that you speed up the recovery process with vitamins or other medications. Opinions about YK-11 are that it really reduces the natural production of testosterone (but does not stop it), so it is important to do at least four weeks of post-cycle therapy.

  • Option for vitamin therapy

If you prefer to take vitamins, you can take Vitamin D3 from 2500 to 5000 iu per day and Zinc 30 for optimal vitamin therapy.

  • Option for therapy with Selective Estrogen Receptor Modulators (SERM)

Clomi-20 at 20-40 mg and Nolva-10 at 10-20 mg per day are enough to strengthen the processes in the body responsible for the production of testosterone and semen.


Myostin YK-11 is one of the best SARM for sculpting the body of the Greek God. We're not kidding! A cycle of one month is enough to transform your body and look better than ever. The thing that distinguishes UK11 from other similar products is that it helps to overcome the bad gene and exceed your capabilities.

Myostine YK 11 blocks Myostatin, which is found naturally in the body and stops muscle growth. This makes it perfect for moments of stagnation when you have reached your capacity. Post-cycle therapy with YK 11 is needed because this SARM greatly inhibits self-testosterone production.
